Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00384008 (Model EVF8212-E) is a 1.5 kW (2 HP) frequency inverter belonging to the 8200 Vector product family. Operating on a 3-phase supply range of 320 V AC to 550 V AC, this AC drive delivers a continuous output current of 3.9 A at 400 V AC and 3.3 A at 480 V AC, with a maximum 60-second overload capacity of 5.9 A (150%). Built in a compact IP20 enclosure for panel mounting inside control cabinets, the unit regulates motor speed across an output frequency range of 0 to 480 Hz. Supported control modes include linear V/f, quadratic V/f, sensorless vector control, and closed-loop vector control, making it suitable for material handling equipment, industrial fans, pumps, and packaging machinery.
Integrating a replacement drive into an existing system requires matching both the primary drive hardware and its installed control interfaces. The EVF8212-E features a modular structure that accepts pluggable function modules for standard control I/O or fieldbus communications, including CANopen, PROFIBUS-DP, DeviceNet, and INTERBUS. Drive configuration and parameter monitoring can be performed via the Lenze E82ZBC XT Keypad or Lenze Global Drive Control (GDC) PC software. Non-volatile internal EEPROM memory can store up to four complete parameter sets, facilitating configuration transfers to replacement hardware. When replacing a failed unit where parameter extraction from a faulty board is needed, ABC Industrial Parts can support configuration recovery and parameter transfer to ensure proper commissioning.
Diagnostic monitoring is provided directly on the front panel via LED status indicators and accessible status parameters. A green LED signals operational readiness and enable states, while a red LED indicates active trip faults or reset procedures. The drive maintains a TRIP memory buffer storing historical fault codes alongside real-time operating metrics like DC bus voltage, motor current, and heatsink temperature. Common operational issues often relate to external conditions such as line voltage drops, motor wiring defects, or fieldbus interruptions. For non-serviceable internal power stage faults, sensor defects, or persistent memory corruptions, sourcing a tested exchange unit from ABC Industrial Parts offers a fast path back to full production.

Programming and Configuration
Parameter setup for the Lenze 00384008 EVF8212-E drive is executed using Lenze Global Drive Control (GDC) PC software or the optional E82ZBC XT Keypad module. Engineering software gives access to all motor parameters, V/f profile adjustments, vector control tuning, switching frequencies, acceleration and deceleration ramps, and digital or analog terminal assignments.
The inverter contains internal non-volatile EEPROM storage designed to maintain up to four distinct parameter sets simultaneously. This multi-parameter architecture enables operators to switch between different operational setups or back up operational settings directly onboard. Saved configuration files can be uploaded using GDC software or copied via the XT Keypad, allowing simple parameter restoration to replacement units.
Communication and System Integration
The EVF8212-E drive features an adaptable interface bay accepting various pluggable function and communication modules. Standard point-to-point control interface is provided through modules like the Lenze E82ZAFSC Standard I/O module. Higher-level automation integration is established through fieldbus modules such as the E82ZAFCC CANopen module, as well as optional hardware interfaces for PROFIBUS-DP, DeviceNet, and INTERBUS networks.
Fieldbus modules interface directly with the main control board to transmit control commands, monitor operational status, and adjust speed setpoints remotely. Address selection switches and network communication settings are stored directly within the drive parameters or hardware rotary selectors, requiring verified bus termination and correct baud rate matching during network commissioning.
Diagnostics and Status Indication
System state monitoring on the Lenze EVF8212-E is managed using front status LEDs, the E82ZBC XT Keypad LCD display, or live monitoring variables within Lenze Global Drive Control (GDC) software. An internal TRIP memory buffer records fault histories, allowing maintenance personnel to inspect fault events and evaluate operational status parameters such as motor current, voltage, and DC bus voltage stored under code index C005x.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED (TRIP / Fault) | Red - Solid or Flashing | Flashes or lights continuously when a fault trip condition occurs. Blinking codes indicate fault state or active fault reset. |
| Green LED (RUN / Ready) | Green - Solid or Flashing | On: Drive operational / enabled. Flashing: Controller inhibit active or operating in standby state. |
Replacement and Spare Part Considerations
When replacing a Lenze 00384008 EVF8212-E drive, verify that the replacement match the required hardware power rating (1.5 kW / 400 V). Pluggable function or fieldbus communication modules from the original unit must be physically transferred to the replacement drive. If a module type differs from what the drive configuration expects, fault code P13 will be triggered until acknowledged via keypad or software.
Parameter sets transferred to the replacement inverter must correspond strictly to the drive hardware size and firmware version. Attempting to load a parameter file designed for a different power class triggers fault code P12. Following parameter restoration, recheck fieldbus node addresses, motor parameters, and safety circuit interlocks before returning the machine to production. For long-term lifecycle planning, the Lenze i550 cabinet inverter series serves as the manufacturer's recommended modernization path.

Frequently Asked Questions
Which programming software is used to configure the Lenze EVF8212-E drive?
The Lenze EVF8212-E frequency inverter is configured using Lenze Global Drive Control (GDC) PC software or locally using the pluggable E82ZBC XT Keypad.
How are parameters restored to a replacement EVF8212-E unit?
Parameters stored in the drive non-volatile EEPROM can be backed up and restored using Lenze GDC software or transferred directly between drives using the pluggable E82ZBC XT Keypad module.
What does fault code OU indicate on the Lenze 00384008 drive?
